To all whom it may concern:

Be it. known that I, Viucln'r H. Daviaox. ii citizen of the United States, und u resident of Goldiield, in the county of Esiueraldii und State of Nevada, have nuide' certain new and useful Improvements in Oiiservatioix-Rnundaboiite, of which the following is u s ication.

.\ly invention reiiites to imprmements in amuiieiiient devices, and it.cousi.-ts in the combinations, conatructiona and errungenienta herein deecribed and claimed.

The main object of my invention ix to provide mi uniuwineiit device, which is espeeiidly udu ited lor use at fairs, expositions, ete., where y u large nqinher of people muy be eiitertuined.

A further object of my invention iii to provide ii sightseeing structure which is capable of elevntinF ii number of penile to a considerable heig it above the groun and thou roiati so us to`give the atrone e good view o the exposition grouni s andthe `atil'rouuding country.

A further object of my invention ia to l cord to an umbrella with cara suspended i. novel liii onda of the rib-like beams and the ieaturee conaiht, for raie and lowri rotettn e device a the arma have been rained Other objects and advantages will ap ar in the followingI apecication, and v be plerticui lerly po ted out in the appended ly invention ia illustrated in the .ac-

This trio-ture is provided with ii central i-hrunhor .4 und with nu nniiular run-wey il. mi shown in Fig. i. llrloiv the substructure is a rhuniber 4 for the nccominodution of ii. Fortiou of the driving mechanism, as will o exphiiiwd litter. In the ehuinher 4 is a footing .'i. dodgm-d to receive the end thrust. of n shaft ti. which extentie upwardly through the have und inlprovided with u threaded poilion 7. Loose y disposed about. the shut't ti is n circular platform 8, which is provided with importing wheels 0 arranged to move in the run-ivo 3. Secured also to the undoiside o! the pi'atform 8 are smaller wheels 10, which bear upon a lute 11 laced across the top portion of t e chain r 2. From Fig. -t it will he seen that I have provided a bearing plete l2, which ia supported on the bnll bearings 12. The main shaft 6 ia providedlnear ita upper part, with a collar 13 (see Pia. 1, 6 and which looeel aurroinda the aft 6, and ia carried b e ball bearings u n a collar t4. whic is tixed to the aha t. A aecond collar 15 is suspended from the collar 13 by means of the inks- 16. To the upper collar 13 is pivotally attached a aerial of -outwurdly extending arma 17, theee arma iiein secured by means of ivut pins 18 ae cleur v shown in Fig. 0. he anna 17 are raised und lowered by menne of the movable arma or braces tti. which arc-hingedat 9a to the nrnis li' u' one end und at the om! end to a.
